nonanal

05/01/2017 - "Nonanal discriminates between smokers and former smokers (with and without COPD) and never smokers."
05/01/2017 - "The COPD group and healthy controls (never smokers and former smokers) showed statistically significant differences in hexanal concentrations, and never smokers and the COPD group showed statistically significant differences in nonanal concentrations. "
05/15/2003 - "Whereas all aldehydes but nonanal were lower in control subjects as compared with other groups, only malondialdehyde distinguished smoking control subjects from patients with chronic obstructive pulmonary disease and could be envisaged as a biomarker potentially useful to monitor the disease and its response to therapy."

01/01/1991 - "Hydrogen peroxide, another product of PC ozonation, did not induce hemolysis; however, a combination of H2O2 and nonanal was significantly more hemolytic than nonanal alone. "
01/01/1991 - "Hemolysis was also observed when RBC were incubated with nonanal, the expected product of the ozonation of oleic acid, the principle unsaturated fatty acid in the liposomes. "
01/01/1991 - "Among different antioxidants tested, ascorbate, catalase, and glutathione peroxidase partially inhibited hemolysis induced by ozonized liposomes and by H2O2/nonanal mixtures, but they were not protective against the nonanal-induced hemolysis. "

10/27/2022 - "With intracellular imaging application, the EC@dye-NH nanosensors demonstrated excellent intracellular uptake and strong green fluorescence emission upon introducing the nonanal into the lung cancer cells (A549). "
04/28/2020 - "We have demonstrated the feasibility of these millimeter-long h-WO3 nanowires for the electrical sensing of molecules (lung cancer biomarker: nonanal) on flexible substrates, which can be operated at room temperature with mechanical flexibility with bending cycles up to 104 times due to the enhanced textile effect."
11/10/2016 - "The gas condenser-GC/MS analysis identified concentrations of 56 VOCs in the breath exhaled by the test population of 136 volunteers (107 patients with lung cancer and 29 controls), and selected four target VOCs, nonanal, acetoin, acetic acid, and propanoic acid, for use with the condenser, GC, and sensor-type prototype system. "
06/01/2010 - "Lung cancer patients could be identified by means of exhaled pentanal, hexanal, octanal and nonanal concentrations. "
06/01/2010 - "Exhaled pentanal, hexanal, octanal and nonanal concentrations were significantly higher in lung cancer patients than in smokers and healthy controls (p(pentanal) = 0.001; p(hexanal) = 0.006; p(octanal) = 0.014; p(nonanal) = 0.025). "

06/26/2023 - "A sample containing a nonanal content above the threshold of 1.04 μL is expected to be COVID-19 positive with a sensitivity and specificity of 87% and 89%, respectively, validated by comparison with RT-PCR results. "
01/01/2021 - "The real-time, non-invasive detection of methylpent-2-enal, 2,4-octadiene 1-chloroheptane, and nonanal in exhaled breath may identify ARDS patients with COVID-19. "
01/01/2021 - "The four most prominent volatile compounds in COVID-19 patients were methylpent-2-enal, 2,4-octadiene 1-chloroheptane, and nonanal. "
06/26/2023 - "During the corona virus disease 2019 (COVID-19) pandemic period, rapid screening of covid-19 patients has been of great interest by developing a fluorescent sensor for complexation with nonanal, which is a marker for Covid-19 detection in sweat. "
10/01/2021 - "Three aldehydes (octanal, nonanal, and heptanal) drew special attention, as aldehydes are also elevated in the breath of adults with COVID-19. "

01/01/2023 - "Given that secondary cancer prevention programs for nonanal cancers are underutilized in sub-Saharan Africa, our objective was to assess concerns for anal cancer and hesitancy with cancer prevention among at-risk Nigerian SGM. "
01/17/2023 - "Headspace levels of seven compounds (hexanal, nonanal, cyclohexanone, 2-nonanone, pyrrole, pyridine, and phenol) were significantly higher above the cancer tissue, whereas eleven volatiles (ethyl acetate, acetoin, 2,3-butanedione, 3-methyl-1-butanol, 2-pentanone, γ-butyrolactone, DL-limonene, benzaldehyde, 2-methyl-1-propanol, benzonitrile, and 3-methyl-butanal) were higher above the non-cancerous tissue. "
01/01/2020 - "Interestingly, H2O2-oxidation of 5-(Z)-dodecenoic acid and 5-(Z)-tetradecenoic acid produced volatile aldehydes that were reported as specific volatiles in breath from various cancer patients, such as heptanal, octanal, nonanal, decanal, 2-(E)-nonenal, and 2-(E)-octenal. "
12/01/2015 - "Twelve VOCs-pentanoic acid, hexanoic acid, phenol, methyl phenol, ethyl phenol, butanal, pentanal, hexanal, heptanal, octanal, nonanal, and decanal-were present at significantly higher concentrations (P < 0.05) in the cancer groups than in the noncancer controls. "
